Frequently Asked Questions

Yes, you can freely convert WebM videos to MP4 for free in your browser. There is no software to install and no account required for simple conversions.

WebM is an open video format designed for web streaming. It typically uses VP8 or VP9 video with Vorbis or Opus audio. So it can be opened on most modern web browsers, but it is not universally supported by every device or editor.

In contrast, MP4 (MPEG-4 Part 14) is a widely compatible digital multimedia container format. It can store data such as video (H.264 or H.265), audio, subtitles, and pictures. Due to its excellent compression effect and wide compatibility, MP4 has become one of the most popular video formats. MP4 also refers to portable devices that can play MP4 videos. These are known as MP4 players. The file extension is .mp4.

Converting WebM videos to MP4 solves common compatibility issues. Many devices, messaging apps, and video editors cannot import or render WebM reliably, while MP4 is nearly universally supported. MP4 videos are also easier to upload to social platforms and insert into slides or documents.

You should not observe a visible difference for normal video use. The WebM to MP4 converter will preserve the original video resolution and frame rate and use efficient encoding so the MP4 looks the same during playback. Minor compression may occur to keep file sizes reasonable, but the output is designed to match the source quality as closely as possible.

Absolutely. All the video files, whether uploaded or downloaded, are kept safe during processing. We use 256-bit SSL encryption, store files in a secure cloud environment, and automatically delete them within 24 hours.

Sure. If your WebM files include audio (soundtrack), the converter carries the sound over to the MP4 automatically. It will keep video and audio in sync. However, if your source has no audio track, the MP4 will remain silent.
